AND logic gate using transistors

AND logic gate using transistors

We build a basic AND gate using two NPN transistors, pushbutton switches, and a few other components. We also observe stray (parasitic) capacitance causing the LED to flash unexpectedly and fix the problem using just one extra resistor.

    The video was very helpful. I would recommend others for doing their projects. The problem with my previous circuit was the led wolf glow without any input ( suspecting a short circuit ) , but I went by the book couldn't understand why.
